Patent FI-923636-A (FI)
Inventor: BUECHLER CHRISTIAN
IPC: G11B7/1378
Filed: 1992-08-14
Abstract: In an optical scanning device, a light beam (L) is focused astigmatically by an objective lens (O) on a record carrier, e.g. a disk (CD), which reflects it onto a four-quadrant photodetector (PD). The astigmatism is produced by an astigmatic element, e.g., a concave or convex cylindrical lens (ZX) or two mutually perpendicular transparent disks located in the beam path. The light beam (L) can be moved radially by a coarse drive. The objective lens (O) can also be moved radially by a fine drive in a direction (W) which makes an angle $g(a) to the normals (R) to the data tracks (S). However, the movement of the objective lens (O) controlled by the fine drive through the angle $g(a) causes imaging defects on the four-quadrant photodector (A, B, C, D), which lead to faulty focusing. To prevent faulty focusing due to imaging defects, a preferred axis of the astigmatic element, e.g., a cylindrical lens or two mutually perpendicular transparent disks, runs parallel to the direction of movement (W) of the objective lens. In the case of a convex cylindrical lens (ZX), the longitudinal axis (LA) is parallel to the direction of motion (W) of the objective lens. In the case of a concave cylindrical lens, the transverse axis is parallel to the direction of motion (W) of the objective lens. In the case of two mutually perpendicular transparent disks, the straight line SG which intersects the two disks is perpendicular to the direction of motion (W) of the objective lens.

Abstract: A system for parking motor vehicles exhibits one or more autonomous parking units (S) which are, in outline, in the form of a sector of a circle. Each unit of this kind is assigned a vehicle lift (10), as mechanical conveying means, having a vertical guide (11) arranged in the region of the vertex of the sector and having a projecting vehicle platform (12) which can pivot over the angle of the sector. The task of the lift (10), within the parking unit (S), is to transport the vehicles vertically and horizontally between an entrance/exit level (1) and parking bays which are located on parking levels beneath and/or above the level (1); the lift (10) is further set up for the radial shifting of the vehicles. Each parking unit (S) is, moreover, assigned means for turning in each case one vehicle on the spot, e.g. one or more rotary platforms (8) on the entrance/exit level (1). The vehicle standing surface (9) of each rotary platform can be optionally lined up in an entrance position, an exit position or such that it is radially aligned with the vehicle platform (12) of the lift. A facility of this type adapts (computer-controlled) very flexibly to various operating situations. When driving out, the vehicles can leave the facility such that they can drive forwards straight away. By virtue of a modular construction method, it is not only round facilities which can be produced, but - always having the same units (S) - also other facility outlines which are adapted to the relevant situation. <IMAGE>

Abstract: The invention concerns a biodegradable starch composition, a process for the preparation thereof, the use of the composition and a process for increasing the degradation rate of intermediate products manufactured from starch derivatives and/or products made therefrom under conditions of biodegradation. According to the invention the composition contains 5 to 99 wt-% of a plastisized starch derivative and 1 to 95 wt-% of a biodegradable fibrous material. The microstructure of the composition is discontinuous and formed by a phase containing the starch derivate and a phase containing the fibrous material and any porosity, and its impact strength is at least 10 % better than the corresponding values of a plastisized starch derivative. The composition may further contain 0.01 to 30 wt.% of a biodegradable polyester, such as polylactide, polycaprolactone or a cellulose ester. According to the invention, the biodegradable starch composition is prepared by esterification of starch with glycerol in order to form a mixture containing starch acetate and acetic acid and then the mixture is blended with a biodegradable fibrous material for producing a composition which has a discontinuous microstructure. The invention provides a melt processible composition having good water resistance and mechanical properties which can be regulated by changing the relative amounts and the qualities of the components of the composition.

Title: Improvements in or relating to winding mechanisms for clocks
IPC: G04B5/20
Filed: 1948-01-13
Abstract: 653,632. Winding spring motors. MAAR, Z. Jan. 13, 1948, No. 1036. Convention date, Jan. 13, 1947. [Class 10] [Also in Group XVIII] A winding mechanism for clocks comprises a pendulum which is suspended in a bearing so as to be swingable in any direction and is connected to motion-transmitting means which wind up the driving spring of the clock. The invention is applied to a clock which is adapted to be mounted on a part of a vehicle so that the pendulum is set in motion by movements of the vehicle. The pendulum 7, Fig. 1, carries a bob 9 and is pivoted at 8 to a part spherical piece 5, Figs 1 and 2, universally rotatably supported by ball bearings 4 in a cup-shaped piece 2. A ratchet wheel 11 is fixed to the barrel arbor 12 of the clock and the barrel has a toothed rim 15. As the pendulum 7 swings its component of oscillation in the plane of the ratchet wheel 11 is transmitted to a pawl or click 10 which steps-on the wheel 11 and its component at right-angles thereto is transmitted by a rod 16, a doublearmed lever 17, 19 and a click 20 to stepon the wheel 11. The main spring is thus wound up. A spring-pressed pawl 23 engages the ratchet 11, and prevents backward rotation of the barrel. In another embodiment, Fig. 3, the part 5 has a rim 26 which is connected by strings 27 to a rod vertically movable in guides 29. Motion of the pendulum in any plane will cause downward motion of the rod and a pawl 28 carried thereby will step-on a ratchet wheel 31 in the winding train of the clock. The clock may be contained in a casing detachably secured to the steering wheel of a motor car, Figs. 4 and 6 not shown.

Title: Improved process and apparatus for the production of hydrogels
IPC: B01J2/08
Filed: 1946-01-15
Abstract: <PICT:0608674/III/1> The continuous setting of an inorganic oxide hydrosol, e.g. silica hydrosol, is effected by introducing the hydrosol into one end of a gelling zone, continuously moving the hydrosol through the zone and correlating the gelling properties and speed of movement of the hydrosol to effect gelation while passing through the zone.  The viscosity of the hydrosol may be increased, e.g. by agitation, passage through a pipe or by heating, prior to introduction into the gelling zone.  In one embodiment, the open bottom of an elongated vertical gelling zone, comprising a tube 14 of rectangular cross-section and having its walls lined with four conveyer belts 15, is temporarily closed while hydrosol is continuously introduced into the open upper portion thereof and opened after at least the hydrosol in the lower portion has gelled, the rate of movement of the belts being controlled to limit the rate of discharge of the hydrogel, which issues as a firm continuous body to be subdivided by crossed cutter wires 21 and 22.  The hydrogel may be discharged from a portion of the gelling zone submerged in a liquid and be subdivided under the surface of the liquid.  After subdivision the particles may be washed.  In another embodiment, the hydrosol is introduced into an inclined or horizontal trough-like gelling zone, closed at its inlet end, a conveyer belt travelling over the bottom of the trough causing the hydrogel formed in the trough to move towards a cutting device comprising rotary arms supporting cutting wires.
